Definitions

  • the invention relates to a shaped steel rolling mill with a duo reversing roughing stand and universal working and F1anschen compression stands combined into reversing tandem groups, and a universal finishing stand provided on the output side.
  • Such a shaped steel rolling mill corresponding to the type is known from the company publication W 2/3115 de SMS SCHLOEMANN-SIEMAG AG.
  • a reversing universal stand as well as a universal finishing stand with corresponding flanges-upsetting rolling mills high performance can be achieved with still moderate construction costs, since each pass of the rolling stock through the reversing tandem group results in two universal passes in conjunction with a upsetting stitch .
  • a universal finishing stand with an upstream flange-upsetting stand is connected for the exact completion of the shaped steel with a high surface quality. However, they are not used in reverse operation and therefore only for one pass.
  • the invention is based on the task of creating a high-performance shaped steel rolling mill of the type specified, in which both the space requirement and the effort required are considerably reduced compared to the type determining rolling mill.
  • Fig. 1 a conventional form steel rolling mill is shown schematically.
  • Blocks heated in a pusher furnace, not shown, are in a reversing roughing stand 1, which is designed as a two-roll stand, in a number of passes, mostly between seven and fifteen stitches, rolled.
  • the preform is passed on to a reversing tandem scaffold group 2, which consists of a universal work scaffold 4, a flange compression scaffold 5 and a universal work scaffold 6.
  • the desired profile is largely approximated by repeated rolling in three or five passes.
  • the rolling stock enters a finished stand group 3, in which the support flanges are brought to the exact desired width again by means of a flange-upsetting stand 7, while the universal finishing stand 8, the final shape of the profile and determines the surface quality of the rolling stock.
  • An infeed roller table 9 leads to the reversing roughing stand 1, a feed roller table 10 is provided between it and the reversing tandem stand group 2, the reversing tandem stand group 2 is followed by a transfer roller table 11, and the finishing stand group 3 is an outfeed roller table 12 downstream, which leads, for example, to a cooling bed.
  • Both the Umkekr roughing stand 1 and the reversing tandem stand group 2 are heavily used for the forming by reversing and thus optimally used. Only the flanging mill 7 and the universal finishing stand 8 are used only for a very small reduction and serve more to secure the desired narrow tolerances of the profile obtained and the surface quality of the rolling stock.
  • the arrangement according to FIG. 2 is used for better utilization of all scaffolding.
  • the roughing from block to Pre-profile caused by a reversing roughing stand 1 which allows a high forming capacity through a large number of stitches, for example five to thirteen stitches.
  • the following reversing tandem scaffolding group has a universal work scaffold 4, a flange compression scaffold 5 and a universal finishing scaffold 8. These three scaffolds are also largely used by reversing at least twice, possibly more often, so that three upsetting stitches and six universal stitches can be achieved with just two reversals. However, the use of this reversing tandem scaffolding group 16 is not driven as high as that of the reversing tandem scaffolding group 2.
  • FIG. 3 A practical embodiment of the compact, high-performance shaped steel rolling mill is shown schematically in FIG. 3.
  • the block-heating pusher furnace 17 with its charging devices is shown as well as a descaler 18 after it.
  • the heated and descaled blocks are fed via an infeed roller table 9 to the reversing roughing stand 1, to which a roller quick-change device 19 is assigned and edging and shifting devices 20 in front and are subordinate.
  • the preliminary profiles are fed to the reversing tandem stand group 16 via a feed roller table 10 which is equipped with a cropping saw 21.
  • the scaffolding 4, 5 and 8 of this group is assigned a scaffolding changing device 22 which allows the scaffolding to be exchanged for refurbished scaffolding, it being possible to install scaffolding intended for duo or universal operation.
  • a downstream run-out roller table 12 leads to a cooling bed 24 via a warm shear 23, which can be used, for example, for splitting billets.
  • the vertical rolls of the universal work stands are slightly double-conical in such a way that their bales taper from their median planes to their roll neck.
  • the profiles rolled here have flange halves slightly bent outwards, so that one speaks of "X" pre-profiles, and only the universal finishing stand contains essentially cylindrical roller balls, so that the flange halves receive a common outer plane and the desired "H “Profile.
